When ice changes to water.
melting or fusion
This state of matter has particles that are far apart.
gas
Define Heat
A flow of energy from an object at a higher temperature to one of lower temperature
three units of measurements FOR temperature and unitof measurement for heat
celsius, fahrenheit, kelvin
Joules
temperature of freezing point?
0 degree celcius
When water turns to ice.
freezing or solidification
This state of matter has a fixed shape and volume.
Solid
____________ is a measure of the average kinetic energy of the particles in a substance.
temperature
what are three methods of heat transfer?
CONDUCTION, CONVECTION, RADIATION
What are three ways that animals keep themselves warm during the winter?
Hibernating, burrowing down in the mud, growing a thick coat, building fat, migration
When a gas turns to a liquid.
condensation
This state of matter takes the shape of its container and has a definite volume.
liquid
Define thermal energy
The kinetic energy of moving particles of matter
explain conduction and give an example
Process of heat transfer through direct contact between materials.
Everyday examples:
a.Metal spoon in hot soup
b.Hot surfaces: hot stove, heat from the stove conducts int your hand, making it feel hot.
c.Ice melting on counter
the process by which the suns energy reaches earth is called?
RADIATION
________________ is the process of changing state from a liquid to a gas.
evaporation or vaporization
Adding heat to matter makes the particles move _______.
faster
The most common way to track a persons temperature
By using a thermometer
explain convection and two give an example?
Heat transfer through movements of fluids
boiling water, heating air
What is the term for the energy that is transferred from one object to another due to a temperature difference?
what is heat?
what is something interesting you learnt today.
...
All particles are __________ to each other. In a solid state, the bonds are the strongest.
attracted
Which has more thermal energy, a match when it's lit, or an igloo?
What is an igloo?
explain the heat method transfer of radiation and give two examples.
The way the heat moves through space without anything to carry it, like air or water. Happens in the forms of waves
Examples:
a.The sun sends out heat and light waves. When these waves reach you, you feel warm.
b.Campfire
c.Heat lamps
how do jackets keep you warm
? explain
material of the coat. our bodies produce the heat and the jacket traps the heat
